Abstract

The present invention provides a CFT pre-forming insert injection molded seat back frame. The CFT pre-forming insert injection molded seat back frame comprises: a pair of frame parts which are coupled to face each other and have fiber reinforced plastic formed therein; and reinforcement parts which are formed on regions that the pair of frames respectively face, and are coupled to each other in multiple locations.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A CFT pre-forming insert injection molded seat back frame, comprising:
 a pair of frame parts which are coupled to face each other and have fiber reinforced plastic formed therein; and 
 reinforcement parts which are formed on regions that the pair of frames respectively face, and are coupled to each other in multiple locations, 
 wherein 
 the reinforcement parts comprise
 a plurality of first reinforcement ribs which are protrusions formed on a first coupling region, and 
 a plurality of second reinforcement ribs which are protrusions formed on a second coupling region, 
 
 the plurality of first reinforcement ribs and the plurality of second reinforcement ribs are coupled to each other by mechanical fastening using a fusion or a fastening bolt, 
 a pointed protrusion is formed downward at an end of the plurality of first reinforcement ribs, and 
 an groove at which the pointed protrusion is fitted is formed at an end of the plurality of second reinforcement ribs. 
 
     
     
       2. The CFT pre-forming insert injection molded seat back frame according to  claim 1 ,
 wherein the pair of frame parts includes
 a front frame which the first coupling region is formed on one surface, and 
 a back frame which the second coupling region facing with the first coupling region is formed, and 
 
 wherein a facing region comprises the first coupling region and the second coupling region. 
 
     
     
       3. The CFT pre-forming insert injection molded seat back frame according to  claim 1 , wherein
 the plurality of first reinforcement ribs and the plurality of second reinforcement ribs have a shape symmetrical to each other. 
 
     
     
       4. A CFT pre-forming insert injection molded seat back frame, comprising:
 a pair of the frame parts comprising a front frame and a back frame coupled to the front frame; and 
 reinforcement parts comprising a plurality of first reinforcement ribs formed on the front frame, 
 wherein 
 the plurality of first reinforcement ribs are protrusions formed at a first coupling region, 
 the reinforcement parts further comprise a plurality of second reinforcement ribs which are protrusions formed on a second coupling region, 
 the plurality of first reinforcement ribs and the plurality of second reinforcement ribs are coupled to each other by mechanical fastening using a fusion or a fastening bolt, 
 a pointed protrusion is formed downward at an end of the plurality of first reinforcement ribs, and 
 a groove at which the pointed protrusion is fitted is formed at an end of the plurality of second reinforcement ribs. 
 
     
     
       5. The CFT pre-forming insert injection molded seat back frame according to  claim 1 , wherein
 the reinforcement parts comprise the fiber reinforced plastic. 
 
     
     
       6. The CFT pre-forming insert injection molded seat back frame according to  claim 1 , wherein
 the pair of the frame parts are manufactured
 by forming to a pre-forming molding by pressing it in order to have a determined shape through the pre-forming molding, and 
 by injection molding the pre-forming molding by using the other thermoplastic while simultaneously forming the reinforcement parts. 
 
 
     
     
       7. The CFT pre-forming insert injection molded seat back frame according to  claim 1 , wherein
 the pair of the frame parts are manufactured
 by forming to a pre-forming molding which the reinforcement parts are formed by pressing it in order to have a determined shape through the pre-forming molding, and 
 by injection molding the pre-forming molding by using the other thermoplastic. 
 
 
     
     
       8. The CFT pre-forming insert injection molded seat back frame according to  claim 4 , wherein
 the reinforcement parts comprise the fiber reinforced plastic. 
 
     
     
       9. The CFT pre-forming insert injection molded seat back frame according to  claim 4 , wherein
 the pair of the frame parts are manufactured
 by forming to a pre-forming molding by pressing it in order to have a determined shape through the pre-forming molding, and 
 by injection molding the pre-forming molding by using the other thermoplastic while simultaneously forming the reinforcement parts. 
 
 
     
     
       10. The CFT pre-forming insert injection molded seat back frame according to  claim 4 , wherein
 the pair of the frame parts are manufactured
 by forming to a pre-forming molding which the reinforcement parts are formed by pressing it in order to have a determined shape through the pre-forming molding, and 
 by injection molding the pre-forming molding by using the other thermoplastic.
